:= Features Automotive R744 Refrigerant Leakage Monitoring Sensor ■ Non-dispersive infrared (NDIR) technology with high reliability ■ Simultaneous monitoring R744 refrigerant leakage and in-cabin C02 concentration ■ Low power consumption, low power mode <1mA ■ Fast response for refrigerant leakage detection ■ Less cross interference with other gases Working Principle Measurement Gas Measurement Range Measurement Accuracy Cubic ACDS-1009 is an automotive gas sensor based on Non-Dispersive Infrared (NDIR) technology, mainly designed to effectively monitor in-cabin C02 concentrations to enable on-demand ventilation control, and ensures vehicle safety by real-time monitoring R744 refrigerant leakage. Cubic ACDS-1009 features fast response, low power consumption, and long lifetime. Facing the implementation of EU F-gas Regulation, it can be widely used in automotive HVAC systems, providing an effective solution for vehicle refrigerant leakage safety monitoring. @ Working principle NDIR (Non Dispersive Infrared) Technology C02 gas has a strong absorption of infrared ray with a specific wavelength. According to the Lambert-Beer law, the infrared absorption is highly correlated to C02 gas concentration. The technology is commonly referred as NDIR (Non Dispersive Infrared) technology. Compared with other technologies like electrochemistry, catalytic combustion, solid electrolyte, semiconductor, NDIR technology advantages: good selectivity, anti-poisoning to harmful gas, fast response and good stability, high signal-to-noise ratio, long life, etc. Average Working Current Resolution Response Time Working Condition Storage Condition Working Temperature Working Voltage Lifetime Communication Normal working mode, <100mA Low power mode, <1mA Cubic Sensor and Instrument Co.f Ltd.
